From here, London leads us through the mostly uninteresting story of his life, from a young boy struggling 'to find his own sound' to his big break in Las Vegas. Threaded through this is a vastly unimpressive array of impersonations. Racing through Rod Stewart, David Cassidy, Elvis Presley, Tom Jones and even Tina Turner, the evening runs like a tribute to the oldies, occasionally dipping into insult as he butchers yet another Johnny Cash classic.
